mb_eregi_replace — Replace regular expression with multibyte support ignoring case

Beschreibung

mb_eregi_replace(
    string $pattern,
    string $replacement,
    string $string,
    ?string $options = null
): string|false|null

Scans string for matches to pattern, then replaces the matched text with replacement.

Parameter-Liste

pattern: The regular expression pattern. Multibyte characters may be used. The case will be ignored.
replacement: The replacement text.
string: The searched string.
options: The search option. See mb_regex_set_options() for explanation.

Rückgabewerte

The resultant string or false on error. If string is not valid for the current encoding, null is returned.

Changelog

Version	Beschreibung
8.0.0	`options` is nullable now.
7.1.0	The function checks whether `string` is valid for the current encoding.
7.1.0	The `e` modifier has been deprecated.

Anmerkungen

Hinweis:
Die interne Kodierung oder die mit mb_regex_encoding() festgelegte Zeichenkodierung wird als Zeichenkodierung für diese Funktion genutzt.

Warnung

Der Modifikator e sollte niemals verwendet werden, wenn mit Eingaben gearbeitet wird, die als nicht vertrauenswürdig gelten. Es erfolgt keine automatische Maskierung wie sie von der Funktion preg_replace() bekannt ist. Wenn dies nicht beachtet wird, führt es in der Anwendung höchstwahrscheinlich zu Sicherheitslücken bezüglich der Ausführung von entferntem Code.

To highlight words in multi-byte text:



<?php

$s = 'Алабала';

$f = 'а';

echo preg_replace('/('.$f.')/iu', '<b>$1</b>', $s);

?>
